-M RTU Plastic Case
The unit can be installed on screws or on DIN rail mounting. Before installing the MOSCAD-M RTU, verify that there is sufficient space around the unit. Allow 20 cm (7.87") from the bottom of the box for the TB connectors. When an RF connector is attached (internal radio models), allow for an extra 10 cm (4"): 2.02 cm (.8") from the top of the box for the RF connector and 8 cm (3.15") for the wires. For models with external radios, allow 8 cm (3.15").

Wall Mounting with Screws

The MOSCAD-M can be mounted on the wall using screws, as shown in Figure 3.
1. Secure two screws (maximum head size 0.9 mm) on the wall, 105 mm apart.
2. Hang the unit on the screws, fitting the two cavities on the back cover of the unit over the
screws (see Figure 3).
The screws used should not protrude from the wall surface by more than 6 mm or by less than 4 mm.

-M – Screw Mount
It is also possible to attach the MOSCAD-M to the wall using the small screw hole at the bottom of case, though this requires dismantling the RTU, which is generally discouraged. Consult Motorola service personnel before opening the MOSCAD-M casing. To mount the RTU:
1. Open the case and dismantle the parts of the MOSCAD-M.
2. Secure the back of the case against the wall using a screw whose diameter is less than
3.5 mm and head size is at least 5.5 mm.
3. Reassemble the parts of the MOSCAD.
Before beginning any disassembly or reassembly procedures, you should be adequately grounded to prevent damage to static sensitive devices in the unit.

Wall Mounting on DIN Rail

For mounting the RTU on a DIN rail, two universal foot elements (Phoenix Connectors MFC PIN UMK-FE) are required. To mount the unit, proceed as follows:
1. Slide the two foot elements into the recesses on the back cover of the unit as shown in
Figure 4. Press until they click behind the snaps that secure their placement. (See zoomed image in Figure 5.)

Connections

Ground Connection

Connect the grounding cable directly to the protective grounding pins 9 and 10 (PGND) in the main power-in connector (see TB1 in Figure 9).

Power Connections

The unit can be connected directly to a 9-30V DC source through the main Power-In connector (see Figure 9) where Pin #1 is + (positive) and Pin #2 is – (negative).
Installation
Verify that all power and ground connections are made in accordance with local standards.
It is recommended to connect the main power supply to the unit with a 3.5 amp fuse on the cable.

Backup Battery Connection

The RTU has a special chamber for 3 “C” alkaline backup batteries (not supplied) that are used to retain the unit’s RAM and Real Time Clock in power fail situations.

Internal Radio Connection - antenna

The internal radio is connected through the 14-pin connector on the Main board inside the plastic housing. Its power is driven from that connector. When an internal radio is installed, Port 3 of the radio cannot be used.

External Radio Connection

Connect the external radio to Port 3 (see Figure 9). Verify that the radio button is set to ON.
The radio signals are driven from the AUX connector in Figure 9.
It is recommended to replace the external radio only when the unit is powered off.
7
If the external radio is connected to an outside power supply, first power on the unit, and then power on the radio.
The auxiliary power supply (maximum 2A) can be changed to 6V,
6.5V, 7.5V, 8V, 9V or 9.6V DC by changing the setting of the P11 jumper located on the Main board. (See markings on the board.) To set the power to 8V, remove the jumper and save for future use.
This is usually set in the factory according to the external power supply of the radio. The default setting is 9V DC. To change the voltage, follow the disassembly instructions in Appendix C, place the jumper and reassemble.

Line Communication Connection

Line Communications are connected through Ports 1 or 2 (see Figure 9.) Port 1 can be programmed as RS485 (1A) or RS232 (1B). Port 2 can be programmed as RS232.

Miscellaneous

Open the Case Door

To open the case door properly, press the two clips (latches) and pull the wing to an open position. The cable cover is opened counter-clockwise to expose the cable connections and the backup battery cover is opened clockwise to expose the battery housing.

Close the Case Door

To close the case door properly, press until the latch clicks. Note that if the batteries in the housing are not inserted properly, the backup battery cover door may not close. If the cable connections are not threaded properly through the cable holes, the cable cover may not close.

Antenna Placement

The antenna is connected to the internal radio through the snap hole on top of the plastic housing (see Figure 9). For models with external radios, screw the antenna onto the radio antenna connector.
Installation
An antenna placed on top of the plastic housing produces strong electromagnetic fields that could be harmful to the electronics of the MOSCAD-M RTU and to people in the vicinity.

Fixed Site Antennas

The antenna installation must comply with the following requirements in order to assure optimal performance and make sure human exposure to radio frequency electromagnetic energy is within the guidelines set forth by the local regulations.
• The antenna must be mounted outside the building.
• Mount the antenna on a tower if at all possible.
• If the antenna is to be mounted on a building, then it must be mounted on the roof.
• As with all fixed site antenna installations, it is the responsibility of the licensee to manage
the site in accordance with applicable regulatory requirements. This may require additional compliance actions such as site survey measurements, signage, and site access restrictions in order to ensure that exposure limits are not exceeded.

12

LED Control

Display On/Advance
When the display is off, pressing the push-button once, momentarily, activates the display. Every consecutive momentary depression of the push-button advances the display to the next page, in the following order: CPU > IO1 (I/O Page 1-DI) > IO2 (I/O Page 2-DO) > IO3 (I/O Page 3-AI) > Page 4 (AO) > Page 5 (User Application Controlled) > Page 6 (Hardware Test Controlled). The next depression of the push-button returns the display to the CPU.
Display Off
The display can be programmed using the Configurator Site Configuration tool to turn off automatically after a predefined period of time if the push-button has not been pressed.
LED Test
When the push-button is pressed continuously for a few seconds, all LEDs light up simultaneously. When the push-button is released, the LEDs turn off.
User Flash Erase
After power-up, all LEDs light up. To erase the User Flash, press the push-button while the LEDs are lit. All the LEDs flash three times. Now, release the push-button.
The MOSCAD-M Unit
Alternatively, press the push-button continuously for at least 40 seconds at any time to erase the User Flash.
User RAM Erase (Cold Restart)
Turn off the power supply, while the push-button is depressed. The next time the unit is powered up, it will perform “cold restart”, which means all data stored in the RAM is erased.
Note: The data that is stored in the Flash (i.e. applications, site configuration, and network configuration) will not be erased.

System Software Downloading

During power up, press the push-button continuously. This will cause the unit to enter bootstrap downloading mode, in which the FLASH is programmed from a PC connected to Port 1 of the MOSCAD-M. The CPU LED will begin to blink at 1 Hz, indicating that the CPU has entered bootstrap downloading mode. If after 120 seconds no bootstrap software is loaded and executed, the normal power-up procedure is performed.

CPU Reset

To reset the CPU when a backup battery is not installed, turn the power supply to the unit off and on again. When a backup battery is installed, follow the Cold Restart method described above.
